Matthew Reed has updated his fantastic TRS32 emulator to v1.20, this time adding Exatron Stringy Floppy emulation support (and increasing the window margin sizes to improve readability).
This is the emulator I use in maintaining the site and in addition to being one of the very few emulators out there which is Windows NT/XP/Vista compatible, it is also the only one which is updated regularly
You can download a copy from Matthew’s web site or from the first entry on the TRS-80.com emulator page.
I heartily recommend you register the emulator (and no, I do not get a penny from that registration; it is just very very good software).
